a
Lookup table" a data structure, usually an array or associative array, often used to replace a runtime computation with a simpler array indexing operation".
its implementation of Object which contains data(which is more versatile but slower then arrays) into array.
a={a:'a',b:exit(),c:22} maps to ['a',exit(),22]
An Array:
In computer science an array[1] is a data structure consisting of a group of elements that are accessed by indexing. In most programming languages each element has the same data type and the array occupies a contiguous area of storage.
Despite what
http://dis.4chan.org/read/prog/1231209853/24,26
says, Objects use arrays because they are faster then any hashtables.
and Array is abstraction of
jmp x,return x.value
which is my switch statement does directly and twice as fast.
